diligaf Posted February 7, 2010 Report Share Posted February 7, 2010 I just bought an Evo 290, was wondering whether the coolant still causes problems with the casing like the old betas, and if so should I change it out for another type of coolant such as motul? Or is this no longer a problem? Quote Link to comment Share on other sites More sharing options...
liviob Posted February 9, 2010 Report Share Posted February 9, 2010 (edited) I had the same question that you asked so i dumped the pasty green factory stuff and refilled the cooling system with fresh antifreeze of a known type. No questions now! Edited February 9, 2010 by Liviob Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 9, 2010 Report Share Posted February 9, 2010 Just for safety's sake I'd recommend using a propylene glycol based coolant like Engine Ice or Silkolene Pro Cool. If the engine does have magnesium parts better to be safe then sorry. Quote Link to comment Share on other sites More sharing options...

If the engine does have magnesium parts better to be safe then sorry. The owner of a company called two2cool says that engine ice and the typical auto coolent use the same propylene glycol.

dan williams Posted February 10, 2010 Report Share Posted February 10, 2010 Ethylene glycol is traditionally used in automotive systems. The real benefit of the premixed propylene glycol coolant, aside from non-toxicity, is it uses deionized water which significantly cuts down on the chemical reactions that are corrosion. Tap water is full of chlorine and fluoride and iron and metallic salts which will pass right through you but wreak havoc on your engine.

crash Posted February 11, 2010 Report Share Posted February 11, 2010 Anyone know how much coolent will be required for a 2008 rev4, Sorry for going off track Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 12, 2010 Report Share Posted February 12, 2010 Should be similar to a Rev3 which is about a quart from empty. Just pour it in till it stops taking it. Squeeze the hoses to work out air bubbles in the system. Then run it a while and after it's run for a bit let it cool and check the fluid again. Fill and forget.

evoboy Posted June 26, 2010 Report Share Posted June 26, 2010 I've just drained my coolent on my Evo and got some Silkolene Pro Cool but I don't know if it is remix out of the bottle it doesn't say or does it need diluting ie 50/50 Quote Link to comment Share on other sites More sharing options...
dan williams Posted June 27, 2010 Report Share Posted June 27, 2010 As far as I know all the propylene glycol coolants are premixed and ready to use. From the Silkolene website PRO COOL Advanced, all-season engine coolant based on propylene glycol for reduced toxicity levels. Formulated with 50% distilled water Quote Link to comment Share on other sites More sharing options...
